Chart Image Options

I am bored and looking into creating my own charting control mainly for the experience in GDI and databinding. I have the rudimentary basics complete that allow me to create an image based on some input parameters. I will eventually get to the databinding portion, but the question I have now is, how to get the rendered image to the client. I currently see two options. 1) Save the image to the Response.OutputStream and set the appropriate response headers so that the binary data renders as an image on the client side, or 2) save the rendered image on the server with a unique identifier and then link to that saved image. I am currently using option #1 and this works, but this means that you always have to point to your handler/custom page/etc. indirectly instead of dropping a control on the page. How does the Microsoft Chart Control that started shipping with the 3.5 framework do it? Is there another option that I have overlooked for getting the rendered image to the client?

Here's a nice one for a Pro to bite into
I have a web form that generates a set of reports including asp chart controls. Clicking on the black title loads the report section into the ajax enabled panel below it. Beautiful! Two Problems though: Sometimes, when the ajax is loading the next report section, all the other charts on the page flicker and sometimes even show a red x (the image disappears). They can then reappear again when another chart loads! 2nd Problem: If I use the html-to-pdf converter, I tell all the panels to bind to the data source (they are repeaters) on page load and show content. I Then convert the resulting datastream to PDF. All the other images on the page load, but the ones for the charts don't. I have looked at the generated code, and they are all linked fine to the correct address of the site and the chart generator url.
A sample image of the working page is below:

Hi,I have a reporting services report that displays a dundas chart, it is a snapshot report executed daily.ÃÂ When displaying the report inside a page viewer webpart or a report viewer web part in SharePoint, the first time after a recent snapshot occurs, the image shows up broken.ÃÂ On refresh of the page the image is visible.

Any ideas or work arounds to get the image to display on the first load of the page or why the imageÃÂ is broken?ÃÂ I've tried different reportÃÂ parameters, Format, ClearSesson with no luck.ÃÂ Viewing the report in Report Manager works fine and also going directly to the ReportServer page is fine.ÃÂ It only occurs when it's inside of SharePoint inside of the Page Viewer or Report Viewer web parts or even if I manually create an iframe in a content editor web part.

Text and image functions operate on TEXT, NTEXT and IMAGE data types. These data types are deprecated with SQL Server 2005 and should be replaced by VARCHAR(MAX), NVARCHAR(MAX) and VARBINARY(MAX) when possible. Alternatively you can also consider storing large string values using XML data type. Text and image functions are nondeterministic.

Future versions of SQL Server will not support TEXT, NTEXT and IMAGE data types. Columns with TEXT / NTEXT data type do not support commonly used string functions such as LEN, LEFT, RIGHT, etc. Furthermore, due to the large size of TEXT data you''re likely to see performance issues if you store such data in the database. However, at times you can''t help but use the TEXT / NTEXT / IMAGE data types (for example when supporting 3rd party databases when you cannot change the schema) - this is when text and image functions come in handy.

.NET provides extensive support for image conversion. Any image can be processed from one format to another. Most common formats to which .NET have support for are .BMP, .EMF, .GIF, .ICO, .JPG, .PNG, .TIF and .WMF.

It's no secret that I am thrilled with the new social features of SharePoint 2010. I am most excited about the new Profile Picture handling. I strongly believe that the more we can show the faces of our colleagues to one another the more connected we will feel. Clearly Microsoft feels that way as witnessed by the many features that make use of the Profile Image like the Activity Feed and Colleagues list

As you learnt from the previous articles to upload image to the SQL Database in ASP.Net 2.0 and stream that image into the memory to retrieve it from the database and display it on the web page. In this article you will learn how to upload images to the MS Access database in ASP.Net 2.0

First of all create an Access Database and place it in the App_Data folder of ASP.Net web site project. Then create a table "tblImg" with the following fields:

Select Printer Options:bullet Printer: Select the printer to print to. Some printer selections work for a variety of printers, such as the "HP PCL" selection which prints to most Hewlett Packard DeskJet, LaserJet and compatible printers.bullet Port: Select between Infrared, Bluetooth, Network printing and Serial (COM1-COM8). Most Windows CE devices only have Infrared and COM1 and need special attachments to use the other selections. USB printing and printing across an ActiveSync connection to a desktop printer is not supported.NOTE: On many Pocket PC devices, you CANNOT use the serial and infrared ports at the same time. This means that if your device is connected to your desktop PC using the serial Sync cable, the Infrared port will not work. You must disconnect the serial connection to use Infrared printing.bullet Color/Mono: Select Monochrome (Black & White) if your printer is not a color printer (or if you wish to print in mono). If your printer has color capabilities AND has a black ink capability, select "4-Color CMYK". If your printer cannot hold both color ink and black ink at the same time, select "3-Color CMY".bullet Paper Size: Select paper size for use. You can choose "Custom" and then set special paper sizes in the "Custom Paper" Width and Height boxes. For printers that use "roll" paper, you can set a maximum paper height of 22 inches.

The AxisTitle class declares properties that define the common appearance settings of a title which is displayed by a particular axis.

Properties exposed via the AxisTitle class allow you to customize common title attributes, such as:

* the axis title's text (Title.Text), * the color and font settings of the title's text (TitleBase.TextColor and TitleBase.Font), * apply antialising (smoothing) to the title's text (TitleBase.Antialiasing), * the alignment of the axis title (Alignment), * the visibility of the axis title (TitleBase.Visible).

I tried to use Microsoft's Membership option for signing up new users and authenticating them on subsequent pages, but it has not worked very well. The biggest issue has been with the REMEMBER ME function. With this checked, I am randomly logged out in the middle of some functions and some pages always show me as not authenticated, while others properly show me as authenticated. I built a site based on VB.

I was wondering what other people are using ro register users and monitor authentication and also if anyone has had better experiences with other solutions.
